Abstract: A portable food container is cooled by a solar powered refrigeration unit and includes a thermoelectric power unit and heat pipes so that the container will be cooled even when there is no solar radiation and will have an even temperature distribution.

Abstract: A method for breaking a nail biting habit includes preventing a patient from moving his tongue into a position to contact the fingernail or fingertip when such fingernail or fingertip is placed in the patient's mouth for the purpose of biting the fingernail.

Abstract: A device for removing a ring from a patient's finger includes a motor driven saw blade that is actuated when a lever and a handle are brought towards each other. The motor driven saw blade cuts the ring so it can be removed from the patient's finger. One embodiment of the device includes two saw blades that are movable with respect to each other so that once a ring is cut, a gap will be defined and an opening element can be inserted between the two saw blades to widen that gap by forcing the saw blades apart. Since the saw blades are in contact with the ring, forcing them apart will widen the gap and permit the ring to be removed.

Abstract: An ullage rod cleaning device includes a unitary, one-piece metal case and a unitary, one-piece foam rubber insert. The case includes brackets that are in abutting contact with edges of the insert, and has a magnet mounted thereon.

Abstract: A toy check out station simulates the action of an actual check out station by including a work supporting surface, a system that simulates the action of a bar code reader system, a cash register and a conveyor system. The station includes a plurality of objects that have identifying discs thereon and which are passed over a field generator. When the field of the generator is broken by the discs, a signal is actuated so that each individual item can have its own code according to the number of discs thereon.

Abstract: A feather duster includes a fan assembly and a dust catching assembly and a turbulence-inducing gap that ensures that dust-laden air will be forced to undergo at least one change of flow direction before entering the dust catching assembly.

Abstract: A fitted sheet includes a hem which completely surrounds the sheet along the perimeter thereof and two drawstrings located in that hem. The drawstrings exit the hem on each side of a transverse centerline of the sheet. Stitching can be included to attach the drawstrings to the sheet.

Abstract: A booster cable assembly includes a plurality of booster cables stored in a container unit on independent reels. The reels are controlled to automatically rewind the cables after use, and to control unwinding and rewinding so that the proper sequence of connection and disconnection will be followed during a jumping procedure.

Abstract: A device used to teach and practice a connected putting stroke includes a putter-like device having a clubhead on one end and a grip on the other end. A light assembly in the clubhead includes three lights that are mounted to focus light beams directly out of the bottom edge of the clubhead at a 90.degree. angle to that clubhead bottom edge so that the light beams are located directly beneath the clubhead. A swing track includes paths and path portions suitable for learning and practicing square-to-square, inside-to-outside and outside-to-inside putting strokes in a connected manner. Locating the clubhead light assembly directly beneath the clubhead bottom edge keeps the golfer's eyes focused directly on the clubhead and thus tends to keep the golfer's hands, arms and body operating as a connected synchronized unit.

Abstract: A bicycle wheel mounting assembly includes an inner sleeve that is hand-threaded onto external threads of a solid bicycle wheel axle. An operating handle includes two cams eccentrically mounted thereon and is rotatably mounted on the inner sleeve to rotate those cams about an axis that extends transverse to the inner sleeve longitudinal axis. An outer sleeve is mounted on the inner sleeve to be moved longitudinally of the inner sleeve by the cams. The inner sleeve is hand tightened onto the axle until the outer sleeve abuts the bicycle wheel, whereupon rotation of the operating handle causes the cams to force the outer sleeve forward so as to force the bicycle wheel snugly against the bicycle frame. A boot is also included, and the entire assembly thus includes quick-release features.

Abstract: A tennis ball retriever includes a return net which is located adjacent to the base of a tennis net and which is oriented to bounce tennis balls back to a player after such tennis balls have impacted the tennis net.
